+ <h1>Welcome to Proj4js</h1>
+ <p>
+This is a JavaScript library that provides methods for coordinate
+transformations between map projections and longitude/latitude,
+including datum transformations, in a web client.
+ </p>
+
+ <p>
+To use the Proj4js, you first create a source and destination Proj4js.Proj
+objects, passing in a projection code (e.g. EPSG:4326).
+You can then use the Proj4js.transform() method, passing in map XY as a point
+object and the source and destination projection objects,
+and it returns the point coordinate in the destination projection.
